Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention generally relates to a wavy-embankment
type contamination-free adhesive tape dispenser, wherein a plastic
made adhesive tape dispenser is composed of two mated and opposite
body halves and has a top forming a cutting opening to which a
cutter is rotatably mounted for lifting open to carry out cutting
or closing for enclosing and the body halves form central bores
having inner circumferences from which positioning rims inward
extend for fitting to an adhesive tape roll to allow controlled
rotation of the adhesive tape roll, whereby with the positioning
rims fit into grooves defined in side faces of a central hub of the
adhesive tape, inner circumferential surface of the central tube is
exposed outside the bores of the body halves to facilitate access,
contact, and assisted positioning of the adhesive tape roll in
withdrawal and cutting of the adhesive tape so that the cutting can
be performed in a stable manner and the whole adhesive tape
dispenser features easy replacement and completely enclosed
arrangement of the adhesive tape to suit the needs of sanitary and
safe application of adhesive tape.
DESCRIPTION OF THE PRIOR ART
[0002] A regular adhesive tape dispenser is constructed as shown in
FIG. 5 of the attached drawings, comprising a main body 21 which is
formed by integrally connecting thin sheet like side boards 22 that
are connected together by a middle-section flat board 23 in such a
way to allow bending to form a U-shaped configuration. A surface of
the bent middle-section flat board 23 serves as a positioning
surface and the flat board 23 has an end forming integrated toothed
cutter 24. The opposing side boards 22 form at centers thereof
projecting counterpart projection and recess fitting structures
that are fit to each other to form a combined axle 25 over which an
adhesive tape roll 20 can be fit and supported to form a rotation
center. The adhesive tape roll 20, after being unwound and
withdrawn, is cut off by the cutter 24. Since the adhesive tape
dispenser body 21 has a side-open configuration and the cutting
edge of the cutter for cutting off the adhesive tape is exposed,
the adhesive tape roll 20 is not in a complete enclosure condition
and is thus easily susceptible to external contamination or
staining with contaminants and this does not suit the need of safe
and sanitary application thereof. This is particularly true for
medical purposes for there is more concern about sanitary operation
and application of adhesive tapes. Further, the cutting edge of the
cutter 24 that functions for cutting is also exposed and it is easy
to cause undesired contact, leading to operation safety regarding
hurting users and damaging the cutter. For the consideration of
sanitary and safe operation in practical uses, and due to the fact
that improper constraint of the adhesive tape during the process of
force application and cutting of adhesive tape may lead to improper
or unsuccessful cutting of the adhesive tape, it often needs to use
a finger to hold down the adhesive tape roll 20 to facilitate the
cutting operation. Apparently, the existing adhesive tape
dispensers require further improvement in view of the above
problems.
SUMMARY OF THE INVENTION
[0003] In view of the fact that the existing structures of adhesive
tape dispenser are not satisfactory in respect of the needs for
safety, practicability, and sanitary operation, the present
invention aims to provide a wavy-embankment type contamination-free
adhesive tape dispenser, which comprises body members that are fit
and mated together to define an interior space in which projecting
positioning rims are provided for fitting into an adhesive tape
roll to allow the adhesive tape to be withdrawn through a cutting
opening that is closable by a cover-like cutter for cutting. With a
central hub of the adhesive tape roll being exposed, accessible,
and contacted by a user's fingers that hold the dispenser body, the
cutting operation of the adhesive tape can be performed in a more
stable and convenient manner and further, the cutting edge of the
cutter, after the cutting operation, can be properly closed and
stored in an enclosed condition. Thus, a complete enclosure of the
adhesive tape is realized and an effect that ensures safe and
sanitary application of the adhesive tape is provided, by which the
drawbacks of the conventional adhesive tape dispensers that do not
provide satisfactory safe, practicable, and sanitary application of
adhesive tape are eliminated.
[0004] The primary objective of the present invention is to provide
an adhesive tape dispenser that has a structure arranged in a
beautified configuration and allows easy assembling and application
of adhesive tape. With a central hub of the adhesive tape roll
exposed outside the dispenser body, assisted positioning for the
rotation and withdrawal of the adhesive tape is realized. Thus, the
application of the adhesive tape meets the needs of complete and
sanitary enclosure. The cutting operation of the adhesive tape can
be done with ready application of force. The cutting edge of the
cutter can be stored in such a way to make the outside appearance
of the dispenser beautiful and satisfying the needs of easy
assembling and sanitary operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] The following descriptions are exemplary embodiments only,
and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0013] The present invention provides a wavy-embankment type
contamination-free adhesive tape dispenser, which is structured to
facilitate the deposition of a roll of adhesive tape into the
adhesive tape dispenser and also offer a practical effect of well
control of cutting and dispensing of the adhesive tape. FIGS. 1-4
of the attached drawings show the structure of the wavy-embankment
type contamination-free adhesive tape in accordance with the
present invention, wherein the adhesive tape dispenser is formed by
mating two symmetrically-shaped body halves 10, of which one body
half 10 forms internally a plurality of protuding positioning pegs
11 that is insertable into and engageable with insertion slots (not
shown) defined corresponding cylindrical projections formed on the
other body half to couple together. The body halves 10 have mating
circumferences respectively forming raised and recessed flanges 12
that are engageable with each other for beautifying the mated joint
of the coupled body halves 10. The combined body of the two halves
10 has a top forming a cutting opening 13 that is slightly recessed
with respect to an outer surface of the body. To provide a desired
structural stiffness and to accommodate an extended segment of
adhesive tape, an extension board 14 is provided under the cutting
opening 13 and has a roughened surface. A free end of the board
borders a tape withdrawal slot 15 with respect to the cutting
opening 13. The extension board 14 has an opposite, fixed end
connected to the body of the combined halves 10 and a pivotal joint
slot 16 is formed in the fixed end of the extension board 14 in a
recessed manner for rotatably coupling with a cutter 17 that has a
configuration matching an outside surface of the body 10, whereby
an end of the cutter 17 is directly and rotatably received in the
pivotal joint slot 16 with a pivot formed thereon, realizing a
rotatable opening/closing structure. On opposite sides of the tape
withdrawal slot 15, the body 10 forms two fastening sections 18
that engage and secures fastening pegs 171 provided on opposite
sides of the free end of the cutter 17, so as to securely retain a
cutting edge 172 that is slightly recessed in the free end of the
cutter inside the wall of the body of the halves 10 without any
exposure to cause undesired contact and hurt of a user and
demonstrating satisfactory real safety of use. Each body half 10
has a central portion forming a bore having a circumference from
which a positioning rim 19 in the form of a closed circumferential
wall extends inward, whereby in mounting an adhesive tape roll 30,
the positioning rim 19 is inserted into a ring groove 32 defined in
a side face of a central hub 31 of the adhesive tape roll 30 to
serve as a rotation support for the adhesive tape roll 30. An inner
circumferential surface of the central hub 31 of the adhesive tape
roll 30 is thus partially exposed outside the central bores of the
combined body halves 10. When the adhesive tape is being withdrawn
outside for use, the central hub 31 is rotated and the rotation can
be readily inspected outside and the user's hand is allowed to
touch the central hub 31 for positioning assistance in carrying out
cutting of the adhesive tape, whereby the application and cutting
of the adhesive tape is made more stable and the cut is neat. The
adhesive tape dispenser is structured in such a way to allow
controlled rotational positioning when the adhesive tape roll 30 is
rotated for withdrawal of the adhesive tape, so that the operation
of the adhesive tape can better suit the needs of safety and
practicability and a novel and practical structure is made with
respect to the existing adhesive tape dispensers.
[0014] The structure of the body halves 10 of the adhesive tape
dispenser in accordance with the present invention feature the
rotary assembling of the adhesive tape roll 30 is realized by
directly fitting the positioning rims projecting inward from the
body halves 10 into the side faces of the central hub 31 of the
adhesive tape roll 30 to have the central hub 31 partly exposed
outside the body halves 10. This may be combined with a desired
change of color the material thereof to make the assembled adhesive
tape dispenser more flexible in respect of vivid coloring, which
enhances the flexibility of visual aesthetics. When the central hub
31 is rotated with the withdrawal of the adhesive tape, unique and
ready visual inspection is provided and positioning assistance for
effective control of the withdrawal speed and extension length of
the adhesive tape is realized, leading to stable and firm
application and cutting of the adhesive tape. The cutter 17 can be
securely retained and positioned on the outside appearance of the
body halves 10 and this makes the outside appearance of the
adhesive tape dispenser beautiful and configurable as circle or
rectangle or other shapes as desired, for the concealed storage of
the cover-like cutter allows it to maintain the outside appearance
of the article and to ensure that the adhesive tape is secured for
being enclosed and the needs of safety for application, cutting,
and carrying are met, so that the adhesive tape is made
contamination free and safe in respect of storage and safety of the
cutter and also offering a practical and sanitary effect in respect
of positioning for cutting. In view of the practical design in
respect of simplified structure and easy and practical assembling,
these features are not found in any of the existing adhesive tape
dispenser. The structure of the present invention is simple,
practical, safe, and offering practical effect of suiting the needs
of sanitary and is a novel design for the structure of adhesive
tape dispenser.
[0015] To summarize, the wavy-embankment type contamination-free
adhesive tape dispenser of the present invention provides a rotary
design by simply fitting positioning rims projecting from central
bores into a central hub of an adhesive tape roll and this not only
offers enclosures sanitary and safe, integral and beautiful storage
of the cutter, but also provides assistance for positioning of the
adhesive tape withdrawn from the dispenser for the extension of a
desired length and the cutting thereof, whereby the needs of
practicability and safety of the application of the adhesive tape
is realized. Through change of color of the central hub of the
adhesive tape roll and the dispenser body, the outside appearance
of the adhesive tape dispenser is made more beautiful. The whole
structure not only offers the effect of use in respect of
structural safety and sanitary, but also meets the need of novelty
of design and assembling, completely suiting the need of modern
people.
[0016] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
